The owl is often regarded as an "ominous bird" in the folk, called the ghost bird, the mourning bird, etc. in ancient books, it is also called the ghost ghost, ghost car, ghost ghost ghost or exile, as a symbol of bad luck and death. The reason for these views may be that owls are strange in appearance, with big, round eyes and bright lights, which make people feel frightened; their ears stand upright, like the mythical double horned monster; and the owl's cry in the dark is as gloomy as a ghost, which makes people feel more terrible.

In addition, owls ambush in the daytime and come out at night. When they fly, they are like ghosts. They often see only a flash of dark shadow, which also makes people who do not know their behavior very well have all kinds of terrible associations.

In Japan, the owl is known as the lucky bird. It also becomes the mascot of Nagano Winter Olympics, representing good luck and happiness. People are afraid of owls and think they can be used to drive away evil. According to this, the domas who destroyed owls used the owl simulation to suppress evil.
